FOLDING BAY-WINDOW.

I SPECIFICATION forming part of Letters Patent No. 436,066, datedSeptember 9, 1890.

Application filed March 81,

To all whom it may concern.-

Be it known that I, CHRISTIAN FREDRICK- SON, a citizen of the UnitedStates, and a resident of Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful. Improvements in FoldingBay- }Vindows, of which the following-is a specifica- This inventionrelates to that typeof folding or collapsible Windows that are adapted,when not required for use, to fold flat against the side of the wall towhich they are attached, as fully set forth in my former Letters Patent,No. 422,585, issued to me March 4, 1890, for improvementinfoldingbay-windows; and the presentimprovementshave for theirobject toprovide an improved construction of square or box-for1n bay-windowadapted to fold together compactly in an easy and ready manner, andwhich is capable of being easily removed to one side from in front of anordinary window when not required for use. I attain such object by theconstruction and arrangement of parts illustrated in the accompanyingdrawings, in which- Figure 1 is a front elevation of my improved foldingbay-window; Fig. 2, a transverse vertical section of the same in itsnormal condition as a bay-Window at the side of a locomofive-cab, &c.;Fig. 3, a similar view of the same in a folded or collapsed condition,and Fig. 4 a horizontal section at line a: 00.

Similar figures of reference indicate like parts in the several views.

As represented in the drawings, my present improved bay-window consistsof a roof portion 1, pivoted at its inner end to the frame 2 and at itsouter end to the pendent portion 3, that forms the front of thebay-window and which in turn is hinged to a lower portion 4, thatconstitutes the bottom or floor of the bay window when the same is inits normal position. The hinge-joints between these parts are arrangedhorizontally, so that the parts will hang or collapse by gravity to thevertical position indicated in Fig. 3 when the window is in itscollapsed condition. The frame 2 will have the usual rectangular windowopening or way, and in the jambs of said opening is pivoted in avertical manner the radially swinging window portions 5, that constitute1890- Serial No. 346,072.

the sides of the bay-window, and it is preferably to make such frames 5of the angular form shownin the drawings, as with such construction itis only necessary in unfolding the present improved bay window to pushthe free ends of said portions 5 outward, as they will, owing to theirformation, lift the sections or portions 1 and 3 into proper position,the bottom section 4 being afterward drawn up by a cord 6 or eye 7 intothe proper position to close the bottom of the window.

8 arehandles on the portions 3 and 5 for handling thesame.

The bay-window portions 1, 3, 4, and 5 will be glazed in any usualmanner, and in the present invention the portions 3 and 5 will be formedwith a central opening or chamber 9, the circular frame of which isconnected to the outer sash by horizontal and vertical rails, as shown.The purpose ofthis construction is to afford an opening through thewindows for the reception of a night-glass, or to constitute a combinedpeep-opening and ventilating-opening, as desired, and in the latter casethe opening will be protected by a swing ing cover 10, as indicated inthe drawings.

The frame 2 may be fixedly attached to the wall 11 of the car, building,850., or constitute a part of the same. It is, however, pre

ferred to make the same laterally adjustable upon slides 12 and 13, asshown in Figs. 1, 2, and 3, so that the bay-window can be moved bodilyfrom in front of the window-opening in the wall of the cab, 85c. 14 areanti-friction rollers on the frame 2, that roll on the top track toreduce the friction in moving the window.

With myimproved construction of window it is evident that the floor orbottom of the window can be left open for the purpose of ventilation,and likewise either of the side portions 5, as one of the same will besufficient to hold the window in an unfolded condition.

In the present construction the lower slide 14 acts as asupporting-ledge for the free end of the window-bottom 4 when the windowis unfolded, as indicated in Fig. 2.

Having thus fully described my said invention,what I claim as new, anddesire to secure by Letters Patent, is-

1. Afolding bay-windowcomprising,in combination, the roof portion 1,hinged to the frame 2, the front portion 3, hinged to the portion 1, andthe vertical side portions 5, hinged in the window-opening,substantiallyas set forth. 2. Afoldingbay window comprising,in combination, the roofportion 1, hinged to the frame 2, the front portion 3,'hinged to theportion 1, the bottom portion 4, hinged to the lower end of the frontportion 3, and the vertical side portions 5, hinged in thewindowopening, substantially as set forth.

3. A folding bay-Window, essentially as herein described, attached toand in combination with a main frame 2, made adj nstable laterally onslides 12 and 13, essentially as herein set forth.

4. In a folding bay-window, essentially as herein described, the windowportions 3 0r 5, provided with a central opening or chamber 9, thecircular frame or margin of which is connected to the window-frame byconnecting-rails, essentially as herein described.

In testimony whereof witness my hand this 20th day of March, 1890.

CHRISTIAN FREDRICKSON.
